Product Details
"The bolt performance grade label consists of two parts of numbers, representing the nominal tensile strength value and yield strength ratio of the bolt material. For example, a bolt with a performance level of 4.6 means:
1. The nominal tensile strength of bolt material reaches 400MPa level;
2. The yield strength ratio of bolt material is 0.6;
3. The nominal yield strength of bolt material reaches 400 × 0.6=240MPa level
Performance grade 10.9 high-strength bolts, after heat treatment, can achieve:
1. The nominal tensile strength of bolt material reaches 1000MPa level;
2. The yield strength ratio of bolt material is 0.9;
3. The nominal yield strength of bolt material reaches 1000 × 0.9=900MPa level"
A nut is a nut, a component that is screwed together with a bolt or screw to tighten. All production and manufacturing machinery must use a component that is divided into several types based on different materials, such as carbon steel, stainless steel, and non-ferrous metals (such as copper).
"Standards are norms, and each country and department has its own standards. The most commonly used standards in our daily business include the following:
GB - Chinese National Standard (National Standard) ANSI - American National Standard (American Standard)
DIN German National Standard (DIN) ASME American Society of Mechanical Engineers
JIS - Japanese National Standard (Japanese Standard) BSW - British National Standard
GB - National standard is one of the numerous standards in China, as well as industry standards, professional standards, and departmental standards. National standards are further divided into GB (mandatory standard), GB/T (recommended standard), and GBn (national internal standard). We usually see mandatory standards such as GB30, GB5783, and so on.
In addition to differences in basic dimensions such as head to edge and head thickness, the main difference among the above standards is the threaded part. GB, DIN, JIS, and other threads are all measured in millimeters, collectively referred to as metric threads. Threads such as ANSI and ASME are called American standard threads in inches. In addition to metric and American threads, there is also a BSW British standard, which also has threads in inches, commonly known as Wyeth threads"
